To alter the device from the ordinary arm-y chair position yshown inFig. l to the resting armchair position (Fig. 2), it suflices to liitthe back and to then push it backwards. The lifting 4of the pivots G andC has the effect of releasing the notches Il from the stop-pins H andcauses the bell crank lever l to pivot, thus moving the pivots t Bforwardly and downwardly. The 'seat thus moves forward by sliding on thepins D and is inclined backwards; at the same time, the levers I.retained by the weight of the seatand by the pull of the springs lprevent the links 6 and pivots G from moving backwards, so `that theinclination and uiting ofthe back depend on the l displacement of thepivots Cabout the pivots A.

'nie mung4 angle or the baci: relativelyto' the' seat is-limited,independently of the connection by the links I and bell crank levers 4,by means of abutment devices comprising, in this example, anarm ilpivoted at L on each bellV crank lever I and connected, by a link Il.tothe back, so that upori tilting of the latter, thearm Il abuts againsta' lug lirigid with the lever i and thus limits the angleof rotation ofthel back about the pivot C.

'Ihe userl can thus rest againstthe back at the same time as on, theseat without causing the v angle formed between these members to becomebackward-rocking movement.

- by rocking movement about the pivots A and'E. the .balance ofthestructure is 'ensured by-the tension of the springs I, balancingthedifferencegof the torques of reverse directions ex- :dby the weightofthe user on the back and greater. Their position is maintained inastable Amannerby the tension o f the springs i.

, To pass from this resting arm-chair position to the couch Vposition(Fig. 3), it is only necessary .for the user to cause a sufficientportion of his weight tobear against the back, thus compelling the unitconstitutedsby the back and the seat, to rock about thek pivots A bystretching the springs l.

In the exampie'mustrated, this backward rocking movement is limited byrubber or like abutments I'l, on which bear bentportions I l of thelinks l, but it is to be understood that it is possible to obtain,:ifdesiredpa'more accentuated In each position then dispensed with and thesprings l being attached to other points of the framework for directlyacting on the back; the opening of the angle formed by the seat and backcan also be limited by any other means than those illustrated; a tensionspring can also be attached, on the one hand, to the rear of the frameof the seat and, on the other hand, to the front cross member of theframework, in order to facilitate the forward displacement of the seatand, consequently, the lifting of the back.

I claim:

l. In a recliningl arm-chair. the combination oi' a stationary mainframework, a movable seat', a movable back, bell cranks pivotallyconnected respectively on both sides of said stationary framework, saidbell cranks eachincluding two arms. one of which is pivoted to the rearend of said seat while the other arm of each bell crank is pivoted tothe lower end of said back, other bell cranks pivotally connected tosaid framework atA each side' of said arm-chair and each 'including ytwo arms, one of the arms of the last mentioned l provided with a notchwhich, inthe erect position of the back, is in engagement with the stoppin, said notch being released from said stop-pin on the lifting of theback.

, 3. A reclining arm-chair as claimed in claim'l, in which abutmentmeans is provided on the framework for limiting the pivoting movement ofsaid back relative to said bell cranks when said back is-lifted andinclined towards the rear-side,

springs for normally pulling the said back andv mentioned bell cranks. f
